3.0 Instructions for Installation and Care

You may install a WOODCO USA clamp in any orientation desired. Prior to installation of the clamp, clean and lubricate the tapered contact surfaces of the hubs and the clamp with extreme pressure grease. Coated bolts and nuts do not require lubrication. Lubricate replacement uncoated bolts and nut bearing surfaces with API 5 A2 thread compound in order to provide proper make up force using the recommended torques.

Keep clamp halves matched and turned so that all marking appears on the same side of the clamp.

When installing, keep the spacing between the clamp halves approximately equal. Put the bolts, nuts, and washers in place and arranged as shown in Figure 4.

Perform the tightening of the nuts so as to draw the clamp together evenly on each side. Tighten the bolts to the recommended bolt torque, reference Table 3 for recommended bolt make up torque for all clamps.

Confirm make up on hubs with SR and BX ring grooves by observing, through the gaps, that the hub faces have come into contact. After make up, clearance between the hub neck O.D. and the clamp I.D. should appear uniform.

Excessive torque to achieve make up indicates some problem with fit or finish (rust on clamp or hub mating surfaces can result in difficulty during make up).

Protect the mating surfaces of hub connections and clamps in the same manner as ring grooves when not in use. Clamps or clamp hubs, if  allowed to rust, lose their dimensional accuracy and finish and may become unusable.
